Isihloko ongakwazisa ngasoAma-valve ebhola e-PVC
Umsebenzi we-valve we-PVC webhola
I-valve yebhola, ingxenye yokuvula neyokuvala (ibhola) iqhutshwa yisiqu se-valve futhi izungeza i-eksisi yesiqu se-valve. Isetshenziswa kakhulu ukusika noma ukuxhuma okuphakathi epayipini. Futhi isetshenziselwa ukulawula nokulawula uketshezi. Phakathi kwazo, i-valve yebhola efana ne-V evaliwe ngokuqinile inamandla aqinile okugunda phakathi komgogodla omise okwe-V kanye nesihlalo se-valve yensimbi ye-carbide enosimende. Amandla e-Shear afaneleka ngokukhethekile imidiya equkethe imicu nezinhlayiya ezincane eziqinile.
Ivalvu yebhola enezindlela eziningi ephayiphini ayikwazi nje kuphela ukulawula ngokuguquguqukayo ukuhlangana, ukuphambukisa kanye nokushintshashintsha kwendlela yokuhamba, kodwa futhi ingavala noma iyiphi ishaneli eyodwa ukuxhuma amanye amashaneli amabili. Le valve ngokuvamile kufanele ifakwe ivundlile epayipini.
Ukuhlukaniswa kwe-valve yebhola: i-valve yebhola ye-pneumatic, i-valve yebhola kagesi, i-valve yebhola yezandla.
Ulwazi Oluyisisekelo
Ukusetshenziswa kwe-valve yebhola ye-pvc ngokuvamile akudluli ku-45 ℃, futhi okuphakathi akuzifanele izincibilikisi eziphilayo nama-oxidants aqinile. Ngokwalesi simo, lolu hlobo lwe-valve yebhola lungasetshenziswa kuphela emanzini angaphansi kuka-45 ° C futhi ingcindezi ingaphansi kwe-1.0mpa.
Uma iqhathaniswa namanye ama-valve, inezinzuzo ezilandelayo.
1. Ukumelana noketshezi oluphansi
I-valve yebhola inokumelana noketshezi okuncane kakhulu phakathi kwawo wonke ama-valve. Ngisho ne-diameter ye-diameter encishisiwe ye-diameter yebhola inokumelana okuncane kakhulu noketshezi. I-valve yebhola ye-PVC iwumkhiqizo omusha we-valve webhola owenziwe ngokwezidingo zoketshezi oluhlukahlukene lwamapayipi odlayo. Izinzuzo zomkhiqizo: isisindo esilula, ukumelana nokugqwala okuqinile, ukubukeka okuhlangene nokuhle, isisindo somzimba esilula, ukufakwa kalula, ukumelana nokugqwala okuqinile, ububanzi bokusebenza, izinto ezihlanzekile nezingezona ubuthi, ukumelana nokugqokwa, ukuqaqa okulula, ukulungiswa okulula.
Ngokungeziwe ezintweni zepulasitiki ze-PVC, ama-valve ebhola epulasitiki ahlanganisa i-PPR, i-PVDF, i-PPH, i-CPVC, njll.
2. I-valve yebhola ye-PVCinokumelana nokugqwala okuhle kakhulu.
Indandatho yokuvala ithatha i-F4. Ukumelana nokugqwala okuhle kakhulu nokwelula impilo yesevisi. Ukujikeleza okuguquguqukayo futhi kulula ukuyisebenzisa.
3. Njenge-valve yebhola ebalulekile, i-I-valve yebhola ye-PVCinamaphuzu ambalwa okuvuza, amandla aphezulu, futhi uhlobo lokuxhumana lwe-valve yebhola kulula ukuhlanganisa nokuhlakaza.
Ukufakwa kanye nokusetshenziswa kwe-valve yebhola: Uma ama-flange emikhawulweni yomibili exhunywe nepayipi, amabhawodi kufanele aqiniswe ngokulinganayo ukuze kuvinjwe i-flange ukuthi ingakhubazeki futhi ibangele ukuvuza. Vula isibambo ngokwewashi ukuze uvale, futhi ngokuphambene nalokho ukuze uvule. Ingasetshenziselwa kuphela ukusika nokugeleza, futhi ukulungiswa kokugeleza akufanelekile. Uketshezi oluqukethe izinhlayiya eziqinile lunganwaya kalula ingaphezulu lebhola.
4. Imisebenzi enamandla:
Uhlobo oluhlakaniphile, uhlobo lokulinganisa kanye nohlobo lokushintsha konke kuyatholakala, futhi ivolumu incane: ivolumu ilingana kuphela nama-35% wemikhiqizo efanayo.
5. Abantu abangasindi nabashibhile:
Isisindo singaba ngu-30% kuphela wemikhiqizo efanayo, futhi ukusebenza kunokwethenjelwa: ama-bearings kanye nezingxenye zikagesi zingeniswa ngaphandle kwemikhiqizo yegama lomkhiqizo.
6. Enhle futhi ephanayo:
Igobolondo le-Aluminium alloy die-casting, elithambile futhi elibushelelezi, amandla aphezulu nokumelana nokugqokwa: ingxube yethusi ekhethekile yegiya lezikelemu, amandla aphezulu kanye nokumelana nokugqokwa okuhle.
7. Isiqinisekiso sokuphepha:
I-1500v ukumelana ne-voltage, i-wire lock ekhethekile yekhebula lokukhiya ilula: ukunikezwa kwamandla kwesigaba esisodwa, izintambo zangaphandle zilula kakhulu.
8. Kulula ukuyisebenzisa:
Ukuhlolwa kwendawo engenawo uwoyela, ingangeni emanzini futhi ingagqwali, ukufakwa kunoma iyiphi i-engeli, idivayisi yokuvikela: umkhawulo ophindwe kabili, ukuvikela ukushisa ngokweqile, ukuvikela ukugcwala ngokweqile.
9. Izivinini eziningi:
Isikhathi esiphelele sokuhamba yimizuzwana emi-5 kuye kwengama-60, engahlangabezana nezidingo zezimo zokusebenza ezihlukene. Intambo yezinga elikhethekile yenziwe ngentambo ekwazi ukumelana nokushisa futhi evimbela ilangabi, engagugi uma ishiswa, futhi iphephile futhi inokwethenjelwa.

Yiziphi amakhono okugcinwa kwe-valve yebhola ye-pvc
★ Uma i-valve yebhola ivuza ngenxa yesibambo esixegayo, cindezela isibambo ku-vise, bese uphendulela isibambo ngokuphambene newashi ukuze usiqinise. Kumele kuqashelwe ukuthi udinga ukuqaphela lapho uqinisa isibambo, ungasebenzisi amandla amaningi, ngaphandle kwalokho i-valve yebhola izolimala kalula.
★ Uma ukuxhumana phakathi kwe-valve yebhola ye-pvc nepayipi lamanzi kungaqinile, ukuvala uphawu akukuhle, futhi kukhona ukuvuza kwamanzi, ungakwazi ukugoqa i-valve ye-tape yezinto eluhlaza endaweni lapho ipayipi lamanzi lixhuma khona ibhola, bese ufaka. i-valve yebhola ngemuva kokujika ukugwema ukuvuza kwamanzi.
★ Uma kukhona ukuvuza kwamanzi ngenxa yokuqhekeka noma ukukhubazeka kwe-valve yebhola, i-valve yebhola endala kufanele ihlakazwe futhi ifakwe kabusha.
Kumele kuqashelwe ukuthi i-valve yebhola ye-pvc idinga ukuqhutshwa ngendlela efanele lapho ihlakazwa futhi ihlanganiswa, futhi amaphuzu alandelayo kufanele enziwe kahle.
★ Ngemuva kokuthi i-valve yebhola ivaliwe, konke ukucindezela ku-valve yebhola kufanele kukhishwe ngaphambi kokuhlakazeka, ngaphandle kwalokho ingozi ingase ibe khona. Abantu abaningi abakunaki lokhu. Hlukanisa ngokushesha ngemva kokuvalwa kwe-valve. Isekhona ingcindezi lapho. Le ngxenye yengcindezi ayikhululwa, engahambisani nokuphepha komuntu siqu.
★ Ngemuva kokuthi i-valve yebhola ihlakazekile futhi ilungiswe, idinga ukufakwa ngokuphambene ne-disassembly futhi iqiniswe, ngaphandle kwalokho izovuza.
Uma ufuna i-valve yebhola ye-pvc ihlale isikhathi eside, kufanele wehlise inani lamaswishi ngangokunokwenzeka. Uma kukhona ukuvuza kwamanzi, udinga ukukulungisa ngesikhathi ngokusho kwamathiphu amathathu esihlokweni, futhi ubuyele ekusetshenzisweni okujwayelekile ngokushesha ngangokunokwenzeka.
